Description

Technical Field

[0001] This utility model relates to the field of protein powder extraction and concentration, and in particular to a protein powder extraction and concentration production device. Background Technology

[0002] In the production of protein powder, including plant protein powder made primarily from soybeans and whey protein powder made from whey, the remaining whey after other dairy processing can be processed into whey protein powder. First, it passes through a ceramic filtration device to separate fat, lactose, and protein. Generally, 700 catties of whey is needed to produce about 5 catties of protein powder, so it needs to be concentrated to about 48%, a high-viscosity protein liquid, and then sent to a spray dryer for further concentration and drying. Since a large amount of water needs to be removed during concentration, a large amount of heat is required. Therefore, we designed a protein powder concentration production device that greatly improves the purification efficiency. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a protein powder extraction and concentration production device, including a purification tank, a steam pipe, and a condenser. The purification tank includes a purification section at the bottom and a steam section at the top. The diameter of the purification section is larger than that of the steam section, and a frustum-shaped transition section is provided between the purification section and the steam section. A stirring rod is provided inside the purification section, and a resistance heating rod is provided on the stirring rod. The top of the stirring rod passes through the steam section and is connected to a stirring motor above the steam section. A steam pipe is connected to one side of the steam section, and the steam pipe is connected to the condenser. A first liquid inlet is provided on one side of the top of the steam section, and a slurry outlet is provided at the bottom of the purification section. A solenoid valve is provided at the slurry outlet.

[0004] The condenser includes an upper heat exchange section and a lower condensation section, which are separated into two compartments by a sealed metal partition. Multiple heat pipes pass vertically through the metal partition. The heat-releasing condensation end of the heat pipe is located in the heat exchange section, and the heat-absorbing evaporation end of the heat pipe is located in the condensation section. A second inlet for inputting whey is provided above the heat exchange section, and the lower side of the heat exchange section is connected to the first inlet through a liquid delivery pipe.

[0005] A water outlet is provided at the bottom of the condenser section, and an air outlet is provided on the other side of the condenser section opposite to the steam pipe.

[0006] The purification tank is mounted on a support frame.

[0007] The stirring rod has four stirring crossbars arranged in a circular array. There are more than one set of stirring crossbars arranged in a vertical direction. Heating rods are vertically arranged on multiple stirring crossbars in the same vertical direction.

[0008] The beneficial effects of this utility model are as follows:

[0009] This device uses resistance heating rods to stir and heat whey, causing it to evaporate and concentrate. The high-temperature steam from the evaporation is then sent through a steam pipe to the condenser section of a condenser for heat recovery. The recovered heat is then used to preheat the concentrated whey, reducing the heat required for subsequent heating. The condensed water flows out from the outlet. This device allows for the recycling and reuse of heat, increasing the concentration efficiency. Attached Figure Description
